Think of all the words that would always appear on the perfect page. Put those in the WITH ALL THE WORDS field.

What words can you think of that might not, help you eliminate those pages? Put those in the WITHOUT field.

If there's a term with synonyms, either of which might appear on the page you're after, put them in the WITH ANY OF THE WORDS field.

Try each of the searches now, and record how many sites you find.As you do each search, take note of what kinds of things turn up. Notice that the more specific the terms you include and exclude, the more focused your search.
